Welcome to the forum. I am sorry to hear that you have been left without telephone service or Broadband. If you send me in your details using the link found in the "About Me" section of my profile, I will look into this for you.
However, Sky have UK call centres.
I believe BT should repatriate all call centres to the UK.
I suggested that to my ELC Newcastle help person when I had an issue, he just laughed in sympathy.
All the best
I would take the offer of help from PaddyB and complete the email
